Title
Evaluation of fenoxaprop-p-ethyl for post-emergence weed control in lowland transplanted rice
L. E. Fabro; Carmela Evangelista 1990
Other claims from this paper (12)
- Intervention effect Fenoxaprop-p-ethyl gave excellent control of Echinochloa crusgalli.
- Intervention effect Fenoxaprop-p-ethyl gave excellent control of E. glabrescens.
- Intervention effect Broadleaf weeds and sedges were unaffected.
- Intervention effect Tank mixing with 2,4-D IBE or sulfonyl urea broadened weed control.
- Intervention effect Tank mixing with 2,4-D IBE or sulfonyl urea raised rice yield significantly.
- Intervention effect Follow-up 2,4-D IBE or sulfonyl urea treatment was equally effective.
- Intervention effect Saturated field conditions produced better herbicide results than standing water.
- Observation Crop phytotoxicity initially ranged from 5 to 10%.
- Observation Crop phytotoxicity peaked at 15 to 25% at seven days.
- Observation Chlorosis stopped progressing and normal green leaves formed by day 14.
- Association Initial crop injury did not reduce rice yield.
- Recommendation The authors consider fenoxaprop-p-ethyl feasible for post-emergence weed control in rice.
